Students who attended Catholic high schools were approximately twice as likely as students who attended public high schools to go on and graduate from college, according to a new report from the U.S. Department of Education’s National Center for Education Statistics.
According to the report, 61.9 percent of Catholic high school students went on to earn a bachelor’s degree or higher by the time they were 8 years out of high school. By contrast, only 31.1 percent of public school students had gone on to earn a bachelor’s degree or higher.
Jeffrey doesn't mention one key reason why that is: Catholic schools get to be selective about the students they enroll, while public schools do not.
A pro-Catholic education website even admits this, citing as one reason for higher achievement rates that "smarter parents send their smarter students to Catholic schools, an effect called pre-selection."
Since Catholic schools are in large part selective, they can also remove students who do not perform well -- and those students usually end up in public schools.
